artery day of procedure tips
Informed by recognized medical guidance
Overview
An artery procedure is a medical test or treatment that looks at your arteries (the blood vessels that carry oxygen-rich blood from your heart to the rest of your body) or fixes a blockage in them. Common examples include coronary angiography (a special X-ray of your heart arteries) or angioplasty (opening a blocked artery with a tiny balloon). This article gives you tips for what to do on the day of your procedure so you feel prepared and calm.
Key facts
- Your doctor will give you specific instructions before the day – follow them exactly.
- You will likely need to stop eating and drinking for a few hours before the procedure – your doctor will tell you when.
- On the day, you will be awake but given medicine to relax you, and the area where the catheter (a thin tube) is inserted will be numbed.
- Most people go home the same day or the next morning, but you will need someone to drive you home.
Artery procedures are very common. Hundreds of thousands of people in the UK have them each year to diagnose or treat heart and circulation problems.
They are most often performed on middle-aged and older adults, but can be done at any age if there is a concern about artery blockages. People with risk factors like high blood pressure, diabetes, or a family history of heart disease are more likely to need them.
Symptoms
- If you have severe chest pain that does not go away with rest or medicine prescribed by your doctor, call your local emergency number immediately.
- If you suddenly have trouble breathing, severe bleeding from the catheter site, or feel like you are going to faint, call an ambulance right away.
- ⚠If the catheter site becomes increasingly painful, swollen, or hot to the touch, or if you develop a fever, contact your healthcare provider the same day.
- ⚠If you notice any new numbness or weakness in the arm or leg where the catheter was inserted, seek same-day medical advice.
Common symptoms
- On the day of your procedure, you might feel nervous or anxious – this is normal.
- You may have mild discomfort at the catheter site (usually your wrist or groin) during and after the procedure.
- After the procedure, you might notice some bruising or a small lump at the insertion site.
Symptoms in children
- Artery procedures in children are less common. Your child's healthcare team will give you age-specific advice for the day of the procedure.
Symptoms in older adults
- Older adults may feel more tired or dizzy after the procedure. Let the nurse know if you feel unwell.
- You may need extra help with moving around and using the toilet on the day of the procedure.
Causes
Main causes
- You are having an artery procedure because your doctor suspects or has found a narrowing or blockage in an artery that could reduce blood flow to your heart or other organs.
- Common reasons include chest pain (angina), a previous heart attack, or abnormal results from stress tests or scans.
Risk factors
- Risk factors for needing an artery procedure include: smoking, high blood pressure, high cholesterol, diabetes, being overweight, lack of exercise, and having a family history of heart disease.
When to see a doctor
See a doctor urgently if:
- If you experience severe chest pain, shortness of breath, or sudden weakness on one side of your body before your scheduled procedure, seek emergency care immediately.
Book a routine appointment if:
- If you have questions about your medicines or what to eat on the day of the procedure, call your doctor's office or the hospital unit ahead of time.
Diagnosis
The need for an artery procedure is usually determined after tests like an electrocardiogram (ECG), stress test, or CT scan show possible blockages. Your doctor will discuss the results with you and recommend the procedure if needed.
Tests that may be done
- Before the procedure, you may have blood tests to check your kidney function and blood count.
- You may have an ECG to check your heart's electrical activity.
- If you have allergies to contrast dye (used during the procedure), your doctor will test or discuss this beforehand.
What to expect at your appointment
On the day of your procedure, you will check in at the hospital, change into a gown, and have a small needle (IV) placed in your arm for fluids and medicine. A nurse will review your medicines and allergies. You will then be taken to the procedure room, where the team will clean and numb the area (usually your wrist or groin). You will be awake but relaxed, and you may feel some pressure but not sharp pain. The procedure typically takes 30 minutes to an hour, but you will be monitored for a few hours after.
Treatment
The main treatment for blocked arteries is the procedure itself – either a diagnostic angiogram to see the blockages, or an angioplasty with or without a stent (a small mesh tube) to hold the artery open. Your doctor will choose the best approach based on your condition.
Self-care at home
- Follow your doctor's instructions about eating and drinking before the procedure. Usually, you must avoid food and drink for 4–6 hours beforehand.
- Take your usual medicines as advised, unless told otherwise by your doctor.
- Arrange for someone to drive you home and stay with you for the first 24 hours after the procedure.
Medical treatments
During an artery procedure, doctors may use medicines to prevent blood clots and to help you relax. Afterward, you may be prescribed blood-thinning medicines (such as antiplatelet drugs) to prevent blockages in the treated artery. These medicines must be taken exactly as your doctor directs – never stop or change them without talking to your doctor.
When is surgery considered?
In some cases, if the blockages are very severe or complex, your doctor may recommend coronary artery bypass surgery (open heart surgery) instead of or after an angioplasty. This decision is made based on your specific situation.
Living with this condition
After your artery procedure, you can gradually return to your normal activities. Your doctor will tell you when it is safe to drive, lift heavy objects, or go back to work. Most people feel fine within a few days, but you may need to avoid strenuous activity for about a week if the catheter was in your groin.
Lifestyle tips
- Quit smoking – your nurse or doctor can help you find support.
- Take all prescribed medicines as directed, even if you feel well.
- Attend all follow-up appointments and cardiac rehabilitation sessions if offered.
Diet and exercise
Your doctor or dietitian will likely recommend a heart-healthy diet low in salt, saturated fats, and added sugars, and rich in fruits, vegetables, whole grains, and lean proteins. Regular physical activity, like walking for 30 minutes most days, is also important. Start slowly and build up as you feel able.
Mental health and emotional wellbeing
It is normal to feel worried or down after a heart procedure. You may feel anxious about another blockage or about changing your lifestyle. Talk to your healthcare team about your feelings – they can connect you with counselling or support groups. If you feel hopeless or very low, please tell your doctor.
Prevention
You cannot always prevent the need for an artery procedure, but you can reduce your risk of future blockages by adopting a heart-healthy lifestyle. This includes not smoking, eating well, staying active, managing stress, and controlling conditions like high blood pressure and diabetes.
Screening programmes
If you have risk factors (such as family history, diabetes, or high cholesterol), your doctor may recommend regular check-ups and tests like cholesterol checks or blood pressure monitoring. There is no routine screening for artery blockages in the general population.
Complications
If left untreated
- If artery blockages are left untreated, they can lead to a heart attack, stroke, or poor blood flow to the legs (peripheral artery disease).
- Untreated blockages can also cause chest pain that limits your daily activities.
Long-term outlook
The outlook after an artery procedure is generally good. Most people have fewer symptoms and a better quality of life. With a healthy lifestyle and medicines as prescribed, many people live well for many years. The key is to follow your doctor's advice and attend regular follow-ups.
